Apparently she travels so much that she often forgets what country she's in at any given time -- or at least that's what we can assume happened when Kendall Jenner threw money at a waitress' face after the woman refused to serve her booze.

According to Page Six, Kendall and her bestie Hailey Baldwin were dining at Mercer Kitchen in New York City last week. When Kendall (who is 18) was refused a cocktail, she "got up and left and did not pay for all the food," which totaled around $60. She didn't leave a tip either, and that's when the waitress, Blaine Morris, took matters into her own hands and followed her outside.

A witness says Blaine ran after the girls and asked them to pay up. That's when Kendall allegedly "took a couple of $20 bills out of her wallet, threw them at the server, and walked away, not even counting if it was enough or if it included a tip."

Oh, and it didn't stop there. The server wasn't going to let Kendall get away with such disrespectful behavior. She supposedly tweeted, "That horrible moment you chase a Kardashian down the street because she forgot to pay her bill to be thrown money in your face."

Damn. Way to call her out! (Her tweets are protected though, so whether or not she actually posted this is debatable.)

Assuming this encounter really took place, one of two things is probably going on here. Again, either Kendall mistakenly thought she was in a city in Europe, where she's of legal drinking age, or she just assumed since she's a member of the Kardashian crew, the rules simply don't apply to her.

I know these girls are kind of well known and all, but it doesn't mean they can act like a couple of spoiled brats and expect to get away with it. Considering how much they both have going for them, it will be a real shame if they let silly behavior completely ruin their reputations -- all before they even reach their 20th birthdays.
